Re: How the workflow after NVRAM battery failure?

‎2017-02-0305:24 AM

Data gets written to system memory and the transactions logged in NVRAM. NVRAM provides battery-backed protection against data loss in disaster situations. Having the data in NVRAM allows the system replay data if lost in system memory before it was flushed to disk. Therefore, losing the battery introduces a risk to losing information in the NVRAM though it would not affect workflow for incoming write requests during normal operation.
